Installation Direction of Non-metallic Fabric Fiber Compensator

In order to make air duct compensator achieve available effect in pipe and all mechanical performance play their right role and extend its use life, please make installation according to the requirements as follows: 
1. Air duct compensator should be installed in pipe in natural conditions and the product distortion by contrived factors should be made in installation, so the products will avoid from early damage and weaker application effect. 
2. When air duct compensator is installed to connect with flange, screw of bolt should stretch to the outside of flange to prevent the rubber (fabric) ball from being scraped by whorl tip. The bolt on the face of each flange should be screwed down equably by thread and it is required that all the degree of tightness should be as consistent as possible. In bad conditions, spring gasket can be added except flat gasket to avoid nuts from loosing.
